JAMES F. MGGARRY, OF CALDWELL, OHIO.

ROAD-GRADER.

SPECIFICATION forming part of Letters Patent No. 239,182, dated March22, 1881.

Application filed October 20, 1880. (No model.)

To all whom it may concern Be it known that 1, JAMES F. MoGARRY, ofCaldwell, in the county of Noble and State of Ohio, have invented a newand useful Improvement in Road-Graders, of which the following is aspecification;

Figure I is a sectional side elevation of the improvement shown inposition for work. Fig. 2 is a side elevation of the improvement shownin position for carriage. Fig. Sis a plan view.

Similar letters of reference indicate corresponding parts.

The objectof this invention is to furnish road-graders so constructedthat they can be readily turned, can be used in narrow places, willthrow no weight upon the horses necks, either when loaded or unloaded,and when dumped can be readily drawn back to the place of loading.

The invention consists in constructing a road-grader of a scraper,draw-rods, a crossbar, a draw-bar, and a wheel, for supporting thescraper when dumped and being drawn from place to place, and a chain forholding the scraper in an inclined position while being ject so far tothe rearward that they can be conveniently grasped to control thescraper while being filled. The lower side of the forward part of thebottom A is beveled and to the said forward part is attached a steelplate, E, to act upon the soil and take the wear. The forward part ofthe upper edges of the sides B are rounded off, as shown in Figs. 1 and2, to serve as runners when drawing the grader from place to place, andare faced with iron to prevent wear.

F are the draw-rods, the rear ends of which are hinged to the outersides of the forward ends of thesides B. The rods F extend for ward at adistance apart a little greater than the breadth of the scraper A B (l,are attached to the ends of the cross-bar G, and are bent inward andforward, and their forward ends are attached to the opposite sides ofthe forward end ofthe draw-bar H. The crossbar G is rigidly attached tothe rear end of the drawbar H, and to the center of the said draw-bar isattached the upper end of the forked "or slotted standard I, to thelower end of which is pivoted a small wheel, J. The standard I isstrengthened by braces K, the rear ends of which are attached to theends of the cross-' bar G, and their forward ends are attached to theopposite sides of the lower end of the said standard I.

With this construction, when the grader is dumped the handles D restupon the end parts of the cross-bar G, so that the said grader will restupon the said cross-bar G and the rounded edges of its sides B, and canbe easily drawn to the place of loading, or from one place to another.

If desired, the wheelstandard I can be swiveled to the draw-bar H, sothat the said wheel will work as a caster-wheel.

L is a chain, the forward end of which is attached to a hook, M, orother support attached to the center of the cross-bar G. The rear end ofthe chain L is attached to the middle part of the back 0 by aneye-strap, N, or other fastening, so as to support the scraper in placewhen in a working position. The rear end of the chain L should beadjustably attached to the back (J, so that it can be convenientlylengthened and shortened to hold the scraper at a less or greaterinclination, as the character of the work to be done may require.

The forward end of the draw-bar H is provided with a hammer-strap, O,and a pin or bolt, P, to receive the double-tree or singletree to whichthe horses or horse is attached.

With this construction the grader can be drawn by a single horse when itis to be used in places where it would be inconvenient or impossible fora team to work.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- 1. In a road-grader, the combination, with thescraper A B O D E and the draw-rods F, of the crossbar G, the draw-barH, and the Wheel I J, substantially as herein shown and described,whereby the scraper will be supported While being drawn from place toplace, as set forth.

and described, whereby thescraper will be held in an inclined positionwhile being filled, 10
